Leptoconops (Holoconops) andersoni Clastrier and Wirth

Leptoconops (Holoconops) andersoni Clastrier and Wirth, 1978: 35 (key; female; fig. female antenna, palpus, spermathecae; California).

Diagnosis. ( Table 13) Body blackish, femora and tibiae blackish, tarsomeres blackish except paler on ventral surface of fore tarsomere 1; palpal segment 3 sensory pit as deep as wide, broadening internally on female (as in Fig. 11 L . knowltoni); clypeus with four setae, median pair <0.5 as far apart from each other as from corresponding lateral setae; mid tarsomere 1 with at least one submedian spine. Female stigma posterior margin convex, distal tip rounded; antenna with 11 flagellomeres; flagellomere 11 without submedian black setae; flagellomere 4 dorsal hyaline sensory seta distal and medial to long black seta, out of axial alignment with corresponding sensory setae on flagellomeres 5–10 (as in Fig. 30 L . sublettei); hyaline sensory setae on flagellomeres 9–10 broadly separated; hind tarsomere 3>1.5× longer than 5; spermathecae ovoid, without caplike diverticulum; cerci>3× longer than wide ( Fig. 1 ). Male unknown.

Distribution. California (Mendocino County).

Adult behavior. Females have been collected from the ears of deer on 17 April and from a calf on 18 May near Hopland, California ( Clastrier and Wirth 1978).
